' To all whom it may mean M Be it known that I," ALFRED T. GHAPLIN,

a subject ofthe King of England, residing 'at- Leicester, Leicestershire, England, have invented certain" Improvements in Shoe- Beating Machines, off w hich the following description, inconnection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating like arts in the several figures.

'This' invention relates to devices for detect'ing'wear-in the moving parts of boot and shoe machinery.

According to' this invention, there is pro vided a tell-tale device, that-is automatis cally actuated by a moving part of the maf chine when that part departs fromits'nor- "mal path of movement by reason of wear or failure in itself, or its support or'its actuating means. Although the invention is particularly applicable, 'andis' hereinafter deconsists-1n t ecombinati'on with a rotary carrier and finlshing tools mounted thereon and having movement relatively thereto tending to wear their mountings of a telltale or signal device normally inoperative and arranged to be rendered operative automatically in responseftoja change in the path of. a tool which is permitted by wear upon its I'no'untmg.

Conveniently, the telltale deviceconnprises amember locatedout of the -normal path of rotation of the tool-but in such proximity thereto that when the said part departsto a predetermined extent from its normal-path the member will be struck by it,

' thus indicating or operating means that indicate to the operator thatwear in the machine iparts has occurred to the extent to which the device is constructed to indicate.

The device maybe arranged to be adjustable sot latthe member m 3. momd into a sition nearer to or farther from the normal path of the tool; TlllS ad ustment provldes means for variably determining the-amount of wear that shall be permitted to the machine parts before the device is actuated.

The, tell-tale device may comprise any suitable means and is preferably Specification of Letters Patent.

shown as a gong, which is actuatedby the o motion of the member or of means controlled by it when the member is operated by the said part. i h The" features of this invention, comprising not only those above indicated but the novel combinations of parts-and details of construction hereinafter set forth, will now be explained more fully in combination with the accompanying drawings and will then be pointed out in the claims. I

l convenient construction according to A present invention is illustrated as applied toa pounding-up machine of the rotary type disclosed in United States Letters Patent No. 1,030,887, dated June 25, 1912. The invention, however, is not to be considered as limited to the particular cons struction described or in its application to the type of machine referred to as it could be embodied in other constructions or applied to other types without departing from the spirit of the invention.

Figure l is a perspective of the back of a pounding-up machine of the type shown in said patent, showing the device of the present invention applied thereto; Fig. 2 is a. de%

tail view illustrating the operation of the device. 7

'The machine to which the invention is herein described as applied comprises a frame 2 provided with bearings in which a horizontal tool shaft a supporting a rotary carrier 6 is continually rotated by any suitable means from the source of power. This carrier (5 consists of two end disks or flanges secured. at a suitable distance apart on the tool shaft i, the space between the two flanges being bridged by rods 8 arranged parallel with the tool shaft and joining the edge port-ions of the flanges. Upon these rods 'niounted in the illustrated machine beating rings 9, or finishing devices t are'carried around with the carrier as the latter is rapidly rotated. A plurality of rings are carried by each rod, and the inside diameter 01" the ings is larger than the diameter of the rods, so that as the carrier re volves centrifugal force normally maintains the rings. at the limit of their outward movement. However, when the'rings 9 contact with the work presented against their peripheries, they are permitted to yield inwardly and also to roll or turn about the rods, thereby forcing the work yieldingly of the carrier. parallel with the surfacedctime, these rods wouldbe worn so thin that they would be in danger of breaking. If

the operator failed to notice tlllSElIld con-.

tinued working the machine, such a condition would be particularly dangerous owing to the high speed, at which the machine works, and might result'in serious injury to the operator and to the machine. Accordingto the present invention the operators attention is directed to a worn condition of the machine bymeans of a tell-tale device which is operated as soon as the wear between the finishing devices and their sup ports has reached a certain amount.

In the construction of telltale device herein described, there is secured to the rear side of the casting 12, as by suitable screws 13 entering the, casting, a small verticallydisposed'bracket 15 formed with a boss 16 through which passes a horizontal pini17 upon which a rocker frame 18 is mounted for movement about the pin'17 as a center. This rocker frame straddles the. boss on' the bracket, being provided on either side of the boss with a hub 19 that receives one end of the said pin. The parallel arms 20 extending upwardly from the hubs and forming part of the rocker frame have thelr upper ends curved forwardto pass through holes 21 made in the. guard 12 for the carrier, the

said ends bein joinedby a horizontal contact bar 22 which is secured to the armsby suitable screws. This bar extends the width scribed by the outermost pointsof the beating r1ngs and is'just clear of the rings when :56 the machine is in proper working condition.

The bar is located inside the guard and is intended to be struck. by any of" the revolv- Hing vbeating rings 9 thatv are farther from the axis of the tool shaft 4 than they would be if the machine were inproper working order and should this contact bar be so struck, a signal is operated-by whichthe op-' erator is notified that the machine'requires attention. In the present constructionthe' contact bar 22 is arranged to warn the operator bysounding a gong 25- and accordingly the rocker frame 18 has secured to its lower end a leaf spring 23 carrying at its free end a knob or clapper 24: adapted to strike the gong- 25 which is fixed to an arm depending from the bracket. In order frame theupper end 0 that the clearance between the contact bar 22 and. the beating rings 9 can be adjusted, a portion of therocker. frame has screwed through it a set screw 26 that is normally held in yielding contact with the surface of the bed plate by a light spring or springpressed plunger 28, the screw 26 being locked in adjusted position by a suitable lock nut. v

In the operation of the machine, the work is supported on" a work rest as explained more. fully in'thepatent and is held by the workman with the surface to be beaten in position to be engaged by the beating members orrings 9 as theyare held outward on thecarrier bycentrifugalforce during the rapid rotation of the carrier 6; When the 7 machine isin good condition and properly adjusted the contact bar is solocated that the beating rings in their passage past the bar just clear the bar and the tell-tale device remains out of operation as long as the beating rings keep to their normal path of'movement and themachineis in proper working order.; Should, however, wear cc cur either on the rods 8 or on the rings9 supported by them, due to the continual rub bing or turning movement between the rods and the rings, the distance fromthe rings to the center of the 'tool'shaft 4 will increase.

As the wear increases the rings will pass nearer to the contact bar, and, according to the adjustment of the, rocker frame by its set screw 26, sooner or later the ringswill contact with the bar. 1 When this occurs, the l rings will make therocker frame vibrate and thelatter will "act. to set. the clapperca'rrying spring 23 in motion, this spring amplifying the vibrations at least sufficiently to cause the clapper to ring the gong 25. In this way theoperator is given notice that the machine requiresattention and it in- .dicates to him either that the, rods of the carrier are worn to 'suchan extent as to be in danger of breaking or thatthe beating rings are worn su-fliciently to require their renewal, or both.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. Amachine of the class described having in combination, a rotary carrier, a plurality of annular series of independently r0; tatable beating. elements disposed about the periphery of, the carrier,and an indicating device comprising a fgong and a rocker which is yieldingly held: in such roximity to said annular series of beating e cments that it is vibrated me.- chanically toenga e said gong when any one of said beating e ements departs from its normal path of movement.

. 2. In a machine of theclass described,a

rotary shoe beater. comprising a carrier and a plurality of annular series of independgently" rotatable beating elements disposed about the periphery of the carrier, a bar extending adjacent to said annular series of beating elements in position to be engaged by any one of the beating elements which for any reason departs from its normal path of operation; a gong, a clapper, a rocker connecting the bar and the clapper, means 'for yieldingly returning the bar into the 10 the carrier, ring-shaped shoe finishing devices loosely mounted on the rods for movement radially thereof whereby they are normally held outwardly by centrifugal force while thecarrier is in motion, a bar extending adjacent'to said finishing devices in position to be engaged by any one of the devices which departs from its normal path of operation, a gong, and a clapper connected with the bar and extending into position to engage the gong when the bar is displaced by the passing of a finishing device which is v out of its normal path, said parts being constructed and arranged to maintain the bar yieldingly in and return it automatically to its normal position after displacement by a finishing device whereby the bar and clapper are vibrated mechanically while a finishv ing device remains out of its normal path of movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
